However, it will also be offering a 5 percent discount on auto coverage to certain customers who switch carriers, the Tribune said. They are also advertising 7 percent off car insurance to people who pay off their full bill.

Allstate's auto insurance premiums decreased 4.6 percent recently, and the insurer is now creating more incentives for consumers to purchase both homeowners and auto coverage with them, the Tribune said. Customers insuring two vehicles and a residence will be offered a preferred package discount with up to 15 percent off car premiums, the Tribune said.

Allstate spokesperson Shaundra Turner told the Tribune that "although homeowners rates will increase between $67 and $82 a year … with the new and deepened discounts Allstate is introducing, current homeowner customers that don't have their auto with Allstate can get discounts of up to 54 percent (on auto) by bringing their auto to Allstate."

It's not uncommon for insurance carriers to offer discounts to customers who purchase multiple types of insurance with them. This is one way that many consumers are able to save money on their monthly bills.
